//
// When defining your own board.cpp, you can put extra code in this
// function if you have anything you want done on reset, before main()
// or setup() are called.

// If there's nothing special you need done, feel free to leave this

// analogRead(), pwmWrite()) translate from pin numbers to STM32
// peripherals.
//
// PMAP_ROW() lets us specify a row (really a struct stm32_pin_info)
// in the pin map. Its arguments are:
//
// - GPIO device for the pin (&gpioa, etc.)
// - GPIO bit for the pin (0 through 15)
// - Timer device, or NULL if none
// - Timer channel (1 to 4, for PWM), or 0 if none
// - ADC device, or NULL if none
// - ADC channel, or ADCx if none
